I think Zendesk is still the best way to report something directly, like a toxic player (include screenshots), or a billing issue, or a game-breaking bug. But yeah, it won’t garner a satisfying response, so just be prepared for that.
While I said earlier that this place isn’t for devs, it’s for us, the things we type and report on are still interesting for them. Threads like this are really good: Update 4.2 Bug Hunt (I’ve also edited it a bit to maybe make it even more useful in the future).
